Latest Patents

Galler's latest patents focus on innovative methods for manufacturing light emitting diodes. One of his patents describes a light emitting diode that includes an n-type n-layer, a p-type p-layer, and an intermediate active zone designed to generate ultraviolet radiation. This design features a p-type semiconductor contact layer with varying thickness and multiple thickness maxima directly located on the p-layer. The n-layer and active zone are composed of AlGaN, while the p-layer can be made of either AlGaN or InGaN. The semiconductor contact layer is a highly doped GaN layer, with thickness maxima having an area concentration of at least 10 cm.

Another patent outlines a method for manufacturing light emitting diodes, which includes growing an n-conductive n-layer, an active zone for generating ultraviolet radiation, and a p-conductive p-layer. This method also involves producing a p-type semiconductor contact layer with varying thickness and applying an ohmic-conductive electrode layer directly on the semiconductor contact layer. The design ensures that the p-layer is only partially covered by the semiconductor contact layer in the top view.
